This abstract discloses an improved battery tester for determining the acceptability of a Lithium Sulfur Dioxide (LiSO/sub 2/) storage battery at a given temperature and with one or more cells therein. The tester is generally made up of a first-comparison circuit having a series of series-interconnected components, namely a comparator, first and second flip-flops, and an AND gate. A first resistor is parallel connected to the first-comparison circuit. A second comparison circuit is also parallel connected to the first-comparison circuit and is generally made up of series-interconnected components, namely a second resistor, a capacitor, a buffer, and a second-comparator. A first switch is connected to the first resistor and a second switch is parallel connected to the second-comparison circuit between the capacitor and the buffer. A logic control arrangement controls the operation of both switches, both comparators, and both flip-flops for testing a battery as to its start-up voltage and performance voltage characteristics all in a relatively short time period. In another embodiment of the tester, it is provided with an analog-to-digital converter, a memory, and a sensor arrangement for enhancing the versatility and reliability of the tester in determining the acceptability of a LiSO/sub 2/ battery.
